23 Claims.

This invention appertains to cartons for eggs and the like, and it is an object of the invention to provide a carton which shall be simple in construction, easy to assemble, and which shall hold the eggs safely against breakage.

Another object of this invention is to provide a carton separable into a plurality of sections, each of which is a complete unit, and wherein the carton, when empty, is collapsible for shipment.

The attainment of these and further objects will be apparent from the accompanying specification taken in conjunction with the drawings forming a part thereof.

In the drawings:

Figure 1 shows a blank piece of pasteboard from which the carton is made;

Fig. 2 is a view of the carton partly erected;

Fig. 3 is a view of the completed carton with its covers closed;

Fig. 4 is an enlarged fragmentary section showing the manner in which the carton covers are secured;

Fig. 5 is an enlarged fragmentary view showing the manner in which the carton is collapsed; and

Figs. 6, '1, and 8 which illustrate a modified form of construction correspond generally, respectively, to Figs. 1, 2 and 3.

Referring now to Fig. 1, the general shape of the blank piece of paper, cardboard, pasteboard or the like, from which the carton is made, is shown. The dotted lines indicate the lines along which the blank is creased for folding, while the full lines indicate the lines along which the blank is cut. The portions into which one part a of the blank is divided have been numbered 1 to '7, the corresponding portions in a second part b of the blank being numbered 1 to 7', respectively. The two parts of the blank are integral in the portions 5-5', but are cut apart elsewhere.

The blank part a is folded along the dotted lines following which the portion '7, which constitutes a securing strip, is pasted to one of the longitudinal sides formed from the blank portion 3. When so secured, the portion 6 forms an intermediate wall lying in a horizontal plane parallel to the plane of the portion 4 which forms one of the carton bottoms. The several portions of the blank b are similarly folded and secured. The two partially erected carton components are then folded along the dotted line 21 whereupon the portions 5 and 5 are brought into adjacent relation opposite one another, their two opposite edges being pasted or glued together at their ends. The

two components of the carton are thus securely held together with the portions 5 5', constituting inner sides which together provide a longitudinal partition.

The intermediate walls formed from portions 00 6 6' are divided into a number o! transverse partitions 8 to 14 inclusive. By folding these partitions down at right angles to the plane of the paper along the dotted lines 15 transverse walls are provided which divide the interior of 05 the carton into a number of cells. The partition 14 is folded along the line 16 and the partition 8 along the line 17. The partitions 8, l1, l12 and 14 each have a projection 19 which engages with a corresponding slit 20 when the partitions are 70 folded down, thus serving to hold them in place and give the carton rigidity. The inner side walls 5-5' each have two upwardly projecting tabs 26 one at each of the points where tongues 25 are to be passed under the triangular webs 75 about which the partitions 9 and 12 fold. The object of these tabs is to facilitate closing of the carton, the tabs 26 directing the tongues 25 to their locking positions as may be seen in Fig. 4. The height of 'che partitions 10 to 14 slightly ex- 30 ceeds the height of the inner side wall 5 with the result that, when these partitions are folded down to position, the lower end of each partition is forced to give way and slightly bend, as may be seen at 30 in Fig. 4. Thus, certain of the parti- 85 tions when folded, are additionally held in place by the frictional engagement of their bent lower edges with the bottom of the carton. A structure corresponding to that just described for the setup portions of the blank parts a is produced also from the several portions of the part b of the same blank.

The complete carton, seen in Fig. 3, may be severed into two sections a and b by inserting a knife between the inner sides 5 5' and cutting 95 those walls at the line 2l, and also at the opposite end of the sides 5-5' where they are pasted together.

The assembled carton, with the intermediate wall 6 6 in horizontal position may be collapsed 100 for shipment by swinging the covers 2 and 2' open into planes common with the corresponding sides 3-3', and moving these walls together by folding down the bottoms 4 4' and intermediate walls 6 6', as partially shown in Fig. 5. It is, of 105 course, understood that the carton is further collapsed from the position shown in Fig. 5 until the covers 2 and 2 come together with the intermediate walls 6 6' resting against the sides 3--3', respectively. 110

Referring now to Figs. 6. 7. and 8 showing a modified form of construction, the blank from which the carton is made is in two parts a' and b integrally connected by a strap 50. The blank is divided by creases or score lines, the part a into a number of portions 41 to 47, and the part b' into a number of portions 4l to 47. which correspond, respectively. and are identical to, portions 1 to 'l and l' to 'I' of the carton previously described. The erection of the carton to the stage shownin Fig. 7 is identical to that shown in Fig. 2. To complete the erection of the carton, the blank parts a' and b are folded around until the inner side Walls 45 and 45 are in adjacent relation opposite each other, the strap 50 then constituting one of the ends which holds the two carton components together. The outer edge 52 of a second strap 51 which is integral with the outer carton side 43 is then pasted to the opposite side 43' to hold together the other ends of the two carton components. The straps 50 and 51 are not joined to the inner walls lii5-45, hence the carton shown in Fig. 8 may be collapsed in the same manner as is the carton shown in Fig. 3. Upon collapsing the carton, as the outer sides 43 and 43' are brought together, the straps 50 and 5l fold outwardly at their respective centers. 4

To sever the carton shown in Fig. 8 into two sections, it is only necessary to cut the two ends, i. e., the straps 50 and 51, since these walls constitute the sole means for holding together the two carton components each of which, when severed from the other, becomes a cellular section complete in itself.

While in Figs. 2 and 'l the transverse partitions 8 to 14 are shown folded down, it is, of course, understood that this is for illustrative purposes only. In the process of erection of the carton, those partitions are not folded down until the inner sides 5-5' have been secured together, or until the strap edge 52 has been pasted to the outer wall 43'. The carton is completed, folded and shipped without the partitions 8 to 14 having been folded down. Those partitions are folded down when the eggs are to be put into the carton.

In compliance with the requirements of the patent statutes, I have herein described certain preferred embodiments of my invention. It is, however, to be understood that the same are shown for illustrative purposes only, and I do not wish to be limited to the precise construction shown.
